1. UmGaqo wokuSebenza

Impompo yeoli yegiya iquka ishaft yokuqhuba, igiya yokuqhuba, ishaft eqhutywayo, igiya eqhutywayo, indlu, njl njl. Iigiya ezimbini ezinenani elifanayo lemesh yamazinyo enye kwenye kwaye zifakwe kwindlu. Ukukhutshwa kwe-radial kunye nokuphela kwendawo phakathi kweegiya kunye nezindlu zincinci kakhulu. Kukho ii-oyile zokungena kunye neendawo zeoli kwizindlu. I-shaft yokuqhuba igxininiswe kwisixhobo sokuqhuba, kwaye i-drive gear ifakwe ngokukhululekileyo kwi-shaft eqhutywayo. Xa i-injini ye-diesel isebenza, i-helical gear kwi-crankshaft iqhubela igiya yokuhambisa kwimpompo yeoli ukuze ijikeleze, kwaye igiya yokuqhuba kwizindlu zempompo yeoli iqhuba igiya eqhutywayo ukujikeleza. Ezi giya zimbini zijikeleza zisiya kumacala ahlukeneyo, kwaye ioyile ihamba phakathi kwamazinyo ize impompoze ukusuka kwindawo yokungena ioyile ukuya kwindawo yokukhupha ioyile. Kwelinye icala legumbi lokungena ioyile, ngenxa yokunganyangeki kweegiya kunye nokususwa ngokuqhubekayo kweoyile, ivacuum yenziwa ukwenza uxinzelelo oluphantsi kwaye ivelise ukufunxa, ukuze ioyile epanini yeoli ingene kwigumbi lokungena ioyile. ngesihluzi phantsi kwesenzo soxinzelelo lwe-atmospheric, nakwelinye icala legumbi lokukhupha ioyile, ngenxa yokuhlangana kweegiya kunye nokususwa okuqhubekayo kweoyile, uxinzelelo lweoyile luyenyuka, kwaye ioli iphonswa ngaphandle koxinzelelo oluthile kwaye icinezelwe kwiindawo zokukhuhlana kwendawo nganye ehambayo.

Ukongeza, ekupheleni kwe-meshing yeegiya ezimbini, ngenxa yobukho beoyile yoxinzelelo oluphezulu kunye nomsantsa omncinci phakathi kobuso besixhobo kunye nendlu, ioyile akulula ukuvuza, oko kwandisa uxinzelelo kwishaft yegiya. , ngaloo ndlela kwandisa ukunxiba kwe-shaft kunye nomngxuma. Ukuze kupheliswe le mpembelelo, ukunyanzeliswa koxinzelelo ngokuqhelekileyo kuvulwa kwikhava yempompo ukwenza ukuhamba kweoli kwi-oyile yokuphuma kunye nokunciphisa uxinzelelo ukuze kufezekiswe umphumo wokunciphisa uxinzelelo. Umthamo wokumpompa i-oyile kunye noxinzelelo lwe-oyile yempompo yeoli yonyuka ngokunyuka kwesantya senjini yedizili. Ivalve yokunciphisa uxinzelelo lweoyile inevalve okanye ibhola kunye nespring esijikelezayo. Ioli ifunxwa ngesihluzo kwaye ithunyelwe kwisihluzo se-oyile. Xa uxinzelelo lonikezelo lweoyile lukhula ngesantya senjini yedizili, ivalve yokukhulula uxinzelelo iyavuleka. Ngeli xesha, ioyile ingena kwicala lokungena ukusuka kwicala lokuphuma nge-bypass ukugcina uxinzelelo oluchaziweyo.

2. Iimpawu zesakhiwo

Isakhiwo esilula, ubungakanani obuncinci, ubunzima obulula, kunye nokuhanjiswa kweoli enkulu. Ipompo ye-rotor ye-cycloid ithatha isakhiwo se-rotor meshing yangaphakathi nangaphandle, kunye nenani elincinci lamazinyo kunye nemilinganiselo yesakhiwo esincinci. Inokwenza i-cavity evaliweyo ngaphandle koncedo lwezinye izinto zokuzihlukanisa, kwaye inenani elincinci leenxalenye.

3. Iimpawu zokuhamba

Ukusebenza okungenamagingxigingxi kunye nengxolo ephantsi. Inani lamazinyo e-rotor yangaphakathi nangaphandle yepompo ye-rotor ye-cycloid ihluke ngezinyo elinye kuphela. Xa zihamba ngokubhekiselele komnye nomnye, isantya sokutyibilika kwindawo yezinyo siphantsi, kwaye i-meshing point ihlala ihamba kunye neprofayili yezinyo ye-rotors yangaphakathi nangaphandle. Ke ngoko, ukunxiba okuhambelanayo kwamazinyo ee-rotors ezimbini kuncinci. Ekubeni i-angle yemvulophu yegumbi lokufunxa i-oyile kunye negumbi lokukhupha ioli lilikhulu, lisondele kwi-145 °, ukufunxa ioli kunye nexesha lokukhupha lanele ngokwaneleyo, ngoko ke ukuhamba kweoli kuzinzile, intshukumo izinzile, kwaye ingxolo ilungile. isezantsi kakhulu kunempompo yegiya.

4. Iimpawu zesantya esiphezulu

Kwiimpompo zezixhobo eziqhelekileyo, ukuba isantya siphezulu kakhulu, intlambo yezinyo iya kuzaliswa ngokungafanelekanga ngeoli ngenxa yamandla e-centrifugal, eyenza "i-cavity", enciphisa ukusebenza kwempompo. Ngoko ke, isantya salo asifane sibe ngaphezu kwe-3000rpm, kwaye isantya se-circumferential singaphakathi kwe-5-6m / s. Kwimpompo ye-rotor ye-cycloid, uluhlu lwe-angle yokufunxa kunye nokukhupha lukhulu. Xa ujikeleza ngesantya esiphezulu, amandla e-centrifugal ahambelana nokuzaliswa kweoli kwintlambo yezinyo, kwaye akukho nto inobungozi "i-cavity" iya kwenzeka. Ke ngoko, uluhlu lwesantya sempompo ye-cycloid yerotor inokusuka kumakhulu aliqela ukuya phantse kwishumi lamawaka eenguquko.
